Ed Schouten commits new MPSAFE tty layer

After a long time of developing the code in Perforce, posting patches for review, patching userland application to remove explicit gropping into the “tty internals”, working with other committers to enhance, test and then test a bit more, Ed Schouten has committed his new MPSAFE tty layer to the FreeBSD kernel:

http://svn.freebsd.org/viewvc/base?view=revision&revision=181905

This removes one of the last remaining barriers of running with a completely “Giant-free” kernel.

Thank you Ed :-)
